DEERFIELD — For 20 years, people have been able to pan for gemstones and dig for fossils at The Rock, Fossil, and Dinosaur Shop.

In April, there will be some changes within the brown building at 213 Greenfield Road — its home for the past 10 years —where a life-size dinosaur figure rears its head.

Owners George P. Marchacos and his son, Adam Marchacos, have hired Deb Williams of New Hampshire to manage an expanding operation. At the same time, the shop is undergoing renovations over the winter.

“It’s getting a facelift. Expanding and improving,” Williams said.

Williams previously worked as the general manager at the Lost River Gorge and Boulder Caves in northern New Hampshire.

The building will be enclosed to extend the shop’s season. Right now, the front side of the building is open. The shop will open full-time April through October and will be able to stay open during Thanksgiving weekend and school vacations in December.

It will also continue to offer its mining, panning, and digging activities it is most known for.

Since the business opened in 1993, it has been popular for its dinosaur artifacts. The shop features fossils from Morocco and China, dinosaur eggs from China, and gem stones from South America.

The shop owners hope to provide more hands-on education and community involvement.

“We are looking to go in a different direction,” Williams said.

Williams said the shop hopes to work with local schools and Scout troops. Students studying geology and history could visit the shop and see up close what they are learning.

Other ideas include having students paint murals related to mining and dinosaurs for the shop or working with Boy Scout troops to help them earn geology badges.

The shop will continue to sell rocks and fossils, but there will be more variety.

“We’re hoping to provide a large audience with materials they might not be able to find without traveling,” Williams said. “It’s just fun.”
